Technical features of TEST-MASTER PRO mobile spectrometer
1、 The TEST MASTER PRO mobile spectrometer is designed for rapid identification and precise analysis of metal materials in industrial settings. Can accurately determine C in steel P、S。
The TEST MASTER PRO has two very stable excitation sources: direct current arc excitation (DC-ARC) in air mode and high-frequency spark excitation (high-frequency SPARK) in argon mode, with wavelengths ranging from 170-680nm, covering both ultraviolet and visible wavelength ranges. Based on the selected excitation mode, TEST MASTER-PRO can perform metal analysis with precision comparable to laboratory spectrometers, as well as fast material sorting with analysis time of only a few seconds. The precise and compact design makes the TEST MASTER PRO multifunctional and capable of meeting different application requirements.

2、 The TEST MASTER PRO adopts fully digital excitation light source technology, with an excitation frequency of up to 500Hz and an excitation voltage of up to 500 volts in spark mode, and a DC current of up to 11 amperes in arc mode. It can be flexibly changed for different substrates and grades; The high excitation intensity and flexible excitation parameter settings enable the TEST-MASTER PRO to accurately analyze matrices and alloys such as Fe, Cu, Al, Mg, Ni, Ti, Zn, Co, etc. The biggest highlight of the instrument is that it can also analyze samples such as "cast iron" that are difficult to excite.

3、 The TEST-MASTER PRO mobile spectrometer adopts the latest CCD solid-state detector technology to read the complete analysis spectrum, representing the latest direct reading spectroscopy technology in the digital age.
The atmospheric pressure spectroscopic system uses 13 CCDs as receivers, with up to 30000 pixels, to achieve full spectrum reception within the analysis band. Each element is analyzed using 1-7 spectral lines for comprehensive output, with a large dynamic range and accurate results. The alternating placement of CCD detectors ensures that all spectral lines within the analysis band are received without any omission, enabling simultaneous measurement of multiple spectral lines of the same element and automatic selection of output.
The UV spectroscopic system adopts a CCD detector with a special UV coating, combined with a 3600g/mm grating, covering a wavelength range of 170-200nm, which can accurately measure UV elements such as C, P, S, B, Sn, etc.

4、 Each CCD detector in the TEST MASTER PRO adopts synchronous real-time digital readout technology (DSP). Compared with traditional sequential readout technology, the analysis time and data stability are greatly improved. Arc mode analysis only takes 2 seconds, and spark mode analysis only takes 4 seconds, fully solving the problem of a large number of detection tasks per day and ensuring that the instrument can complete 500 excitations within 1 hour.

5、 The TEST MASTER PRO mobile spectrometer automatically scans spectral lines with its optical system during each excitation, ensuring accurate reception and eliminating the tedious task of peak scanning.

The full spectrum technology automatically traces and adjusts the optical path. When exciting the sample, the instrument automatically recognizes specific spectral lines on each CCD, compares them with the original storage lines, determines the drift position, and finds the current pixel position of the analysis line for measurement. Eliminate spectral drift caused by temperature and pressure changes; The traditional use of photomultiplier tube technology requires manual fine adjustment of spectra, which has high technical requirements. Full spectrum technology automatically and quickly addresses, avoiding laborious manual operations and human errors.

6、 The TEST-MASTER PRO mobile spectrometer adopts full spectrum direct reading (TSA) technology, which makes it very convenient to add spectral lines, increase the matrix, and record metal sample fingerprints. It can achieve multi matrix analysis without adding hardware facilities.

Customers can add analysis matrices and element types to the instrument according to their actual needs during use, and these tasks can be easily completed on the user's site. Compared to similar spectrometers that use PMT technology, it requires extensive hardware modifications. Due to the configuration limitations of the initial instrument, it may not be possible to add the matrix or elements requested by the customer.

7、 The TEST MASTER PRO mobile spectrometer adopts the high-performance specially designed fiber optic technology (HPC Fiber) developed and exclusively used by Oxford Company.

Due to the high-energy and high-temperature state of the spectrometer during the excitation process, ordinary quartz fiber optic cables will experience a sharp decline in performance due to overexposure (Solarization) under these working conditions. Generally, the signal transmission ability of the fiber optic cable will decrease by more than 90% after one month of operation. Greatly affecting the performance of the spectrometer. Oxford Instruments' HPC fiber optic application breakthrough technology solves this problem, ensuring that the fiber optic can work stably in its optimal state for a long time.

Due to the long-term stable operation of optical fibers in signal transmission, the instrument has performed well in testing ultra-low carbon and other trace element applications, allowing customers to use mobile spectroscopy to complete sorting and identification of L-shaped steel (304/304L, 316/316L) on site.

8、 The TEST-MASTER PRO mobile spectrometer adopts jet electrode technology (JET TREAM). In the excited state, an argon gas jet will form around the electrode. This technology will bring the following advantages.

The argon gas flow around the excitation point ensures that the excitation process is not affected by external interference
Saved the use of argon gas and reduced the customer's operating costs
Small samples such as wires can also be easily analyzed without the need to load any adapters

9、 The excitation probe design of the TEST-MASTER PRO mobile spectrometer is very clever, fully considering the practical application needs, providing users with four options: arc probe, ordinary spark probe, ultraviolet (UVPRO) probe, and industrial automation probe.

The arc probe has low requirements for sample preparation and fast analysis time, mainly used for metal sorting and grade identification.
Ordinary spark probes have high requirements for sample preparation and long analysis time, mainly used for precise composition analysis of metal materials. At the same time, users can also analyze the carbon (C) content in black metals in spark mode, with a detection limit of 100ppm.
If users' daily applications require precise analysis of ultraviolet spectral elements such as carbon (C), phosphorus (P), sulfur (S), boron (B), tin (Sn), etc. in black metals, they can choose UVPRO probes. The UVPRO probe is equipped with an argon flushing chamber based on the original probe technology, specifically designed for the analysis of ultraviolet elements, with a detection limit of 50ppm for carbon (C), phosphorus (P), and sulfur (S).
For customers with automation requirements, the detection speed, detection effect, and stability in complex working environments are very important. The automation of mobile spectrometers can solve these problems well. The TEST MASTER PRO has designed a unique automation probe for industrial automation needs. This probe is very easy to assemble on any production line to achieve automated analysis of the production line, and has two modes to choose from: arc and spark.

10、 The cooling part of the TEST MASTER PRO adopts a new innovative design, equipped with two-stage electric refrigeration technology with heat exchangers (Peltier refrigeration technology), abandoning conventional cooling fans and air convection devices. The heat is dissipated through specially designed liners, effectively achieving non moving component cooling without changing the internal structure of the instrument.
The non air circulation cooling method completely prevents external dust from entering the interior of the machine. The instrument casing is made of steel material to ensure optimal stability and electrical safety, and to prevent adverse environmental conditions from affecting the instrument.

11、 The operating software of the TEST MASTER PRO mobile spectrometer is based on the Windows XP system, which is very simple and easy to learn. It is also equipped with three versions: Chinese, English, and German. Operators without any background in spectral instrument knowledge only need simple training to operate the instrument.

12、 The design of the TEST MASTER PRO mobile spectrometer fully embodies the combination of humanization and modern technology.
The instrument design includes the latest DSP technology, CCD technology, and Windows XP operating system, which reduces the subsequent maintenance cost of the instrument while also retaining good scalability.
The industrial touch screen design of the instrument overcomes the constraints of inconvenient on-site mouse and keyboard operation, with clear and intuitive display of large-sized specifications, allowing for remote observation.
The main components of the instrument adopt a plug and play design, which can be quickly disassembled when necessary, fully reflecting the mobility characteristics.
